Rare Hantavirus Strain Raises Human-to-Human Concern
13 May
Summary
- Hantavirus can spread between people via prolonged close contact.
- Rodents are the primary carriers of most hantavirus strains.
- Americans are advised to take precautions when cleaning enclosed spaces.
An hantavirus outbreak originating on the MV Hondius cruise ship has prompted health officials to investigate the potential for human-to-human spread of the virus. The Andes strain, identified in this outbreak, is notably capable of transmission between people through prolonged close contact. Most hantavirus infections in the United States are linked to contact with infected rodents, primarily deer mice, and their waste products.
Exposure typically occurs through inhaling contaminated particles or touching contaminated surfaces before touching the face. Areas like garages, sheds, and cabins are high-risk if rodents have nested there. Health experts recommend precautions, such as wearing a mask and using bleach solutions when cleaning potentially infested spaces, to prevent infection. While the virus is rare in the U.S., particularly in areas like Texas, vigilance is advised, especially when entering seldom-used buildings or handling potential rodent habitats.
